The estimated energy binding for the betanin compound versus the Bcl2 receptor.

Energy Components (kcal/mol)
Protein Complex	ΔEvdW	ΔEelec	ΔGgas	ΔGsolv	ΔGbind
Betanin-Bcl2	−42.42 ± 0.36	−152.86 ± 1.63	−195.28 ± 1.61	154.34 ± 1.37	−40.94 ± 0.42

∆E_vdW = van der Waals energy; ∆E_ele = electrostatic energy; ΔG_gas = the change in the Gibbs free energy of the gas; ∆Gs_olv = solvation free energy; ∆G_bind = calculated total binding free energy.
